I have tested YMTiny on 4 devices (Sony Ericsson k750i, HTC P3600i, Nokia 6600 and Nokia 7390) and surprisingly YMTiny work perfectly on those device. But at the same time, YMTiny won’t work on Nokia 6230.

From my opinion, YMTiny v1.1 is even better than IM+ All-in-One Mobile Messenger v4.22 (comparisons has been made on Yahoo! Messenger features only) based on their user friendly features and graphical user interface.
